GM324 LOW POWER QUAD OPERATIONAL AMPLIFERS Features Description The GM324, a quad internal frequency compensated operational amplifiers with true differential inputs, which operate from a single power supply over a wide range of voltages. They have several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3.0V or as high as 32V with extremely low quiescent current (on a single amplifier basis). The common mode input range includes negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes negative power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, the GM324 can be directly operated of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies. Internal frequency compensated for unity gain Large DC voltage gain 100 dB Wide bandwidth (unity gain) 1MHz (Temperature compenstated) Power Supply Range: Single supply 3V to 32V Very low supply current drain (700 µA)essentially independent of supply voltage Low input biasing current 45 nA (temperature compensated) Low input offset voltage 2 mV and offset current: 5 nA Load Regulation 0.4% max. Input common-mode voltage range includes ground Differential input voltage range equal to the power supply voltage Large output voltage swing 0V to VCC 1.5V The GM324 is available in DIP-14 and SOP-14 packages.
